I have a 1993 cad. Deville. About 2 years ago I had the sensors replaced because the serv. Engine light was on. This corrected the problem but now have the problem again. Can I replace the sensors myselfand if so where are they located? Its a93 cad deville with a 4.6 engine

I am sorry but I don't answer pm's, you wrote:

have a service eng. Light and poor gas milage. Had not had codes checked last time I had this problem I had to have the maf?Sensor and o2 sensor replaced now have the same problem again. The engine has a small miss also

The problem might not be the same and would hate to see you throw money at it and not fix it. If you could run a diagnostic check and see what codes you get, would realy help out. Is your same problem is your engine light is on becouse there are a lot of sensor's that could turn on the light.
